After spending 4 hours going from v12.5 to v14 (note to developers, please make upgrades easier). I am now trying to get my presence and switchboard function of the 3CXPhone for Windows. I have opened every port I can find to do with 3CX (80, 443,5000,5001, 5060, 5061, 5090, 5484, 9000-9500) 3CX phone registers and is able to make calls to both internal (to other extensions) and external (to outside numbers) just fine. I have read other posts: could-not-establish-a-connection-43569.html Still have not been able to get this working. Any other suggestions?
